What is urgent dormer leak detection?
Detecting an urgent dormer leak means immediately and specifically identifying where water is entering your dormer and why it is happening, so that you stop damage and targeted repairs can take place. At Ultrices Leak Detection, we combine building physics such as capillary action, vapor transport, and dew point with professional leak detection to isolate the root cause within a short time. We investigate connections between tiled roofs and side walls, flat roof coverings such as EPDM or bitumen, window frames and fascia boards, concealed gutters, and lead flashing. Our team works according to NEN 2778 and NEN 2779 principles for moisture and watertightness, is VCA VOL and NEN 3140 certified, and delivers an expert report that your insurer understands and accepts. We are on-site within an hour, without any demolition work, with a 99 percent success rate and a guarantee of coverage. Call or WhatsApp 085 080 55 42 or email info@Ultriceslekdetectie.nl for immediate nationwide deployment.
Causes of dormer leaks that we urgently trace
A dormer has multiple critical connections and materials that can fail under the stress of rain, wind, and UV radiation. We focus on the root cause, not just the visible consequence. Consider cracking in EPDM, open seams in bitumen, damaged roof tiles or battens at the connection, rusted tile hooks, a leaking concealed gutter, poorly installed lead flashing along the side walls, open sealant joints around Velux or Fakro roof windows in the dormer, hairline cracks in the fascia board, or condensation due to inadequate ventilation mimicking a leak. Using FLIR thermography, moisture measurements with Protimeter, and a controlled water test, we locate the actual source of the ingress.
- EPDM or bitumen damage: microcracks, detached overlaps and shrinkage cracks on the flat roof surface of the dormer
- Lead flashing and side cheeks: capillary leaks at connections with masonry and wood, or cracked lead due to settlement
- Concealed gutter and valley gutter: blockages, capillary bridges or leakage at seam transitions and end bulkheads
- Window frame and fascia board: open sealant joints, wood rot and leaking screw holes at the dormer frame
How to detect an urgent dormer leak without hacking or breaking.
We combine measurement methods that leave your dormer intact, ensuring quick and targeted repairs. Using infrared thermography, we visualize thermal bridges and moisture traces. A smoke test or dye tracer reveals flow paths in concealed gutters and under roof tiles. Ultrasonic measurements and endoscopy provide insight into cracks and cavities without disassembly. We perform an interim water test, wetting segment by segment according to protocol to precisely delineate the leak line. Our approach prevents unnecessary costs and accelerates definitive repairs by your roofer or contractor.
- Thermography: detection of moisture patterns and heat loss around seams, gutters, and connections
- Smoke and coloring: insight into flow routes in concealed gutters and under overlaps
- Endoscopy: visual inspection in cavities behind the fascia board and under the roof covering
- Moisture and salt measurement: distinction between condensation and actual water ingress for correct diagnosis
Our protocols and techniques for dormer leak detection
We work with a fixed protocol that aligns with NEN guidelines for moisture and building physics and use equipment from brands such as FLIR and Protimeter. This ensures reproducibility, safe execution, and a report that is acceptable to insurers. You benefit from a no-cure, no-pay policy and a 100 percent risk-free inspection.

Common situations and case studies from practice
In the Randstad, we found multiple shrinkage cracks in a bitumen dormer, allowing rain to flow in through the overlaps during westerly winds and become visible through the plaster ceiling. In Brabant, a concealed gutter turned out to be clogged, leading to overflow behind the roof tiles during heavy downpours. In Utrecht, we discovered that condensation caused by insufficient ventilation around a skylight was keeping the wooden frame wet, seemingly mimicking a leak. Thanks to a root cause approach and clear reporting, repairs could be carried out quickly, followed by reimbursement via the buildings insurance. This keeps costs manageable and prevents subsequent damage to insulation, interior finishing, and the structure.

Frequently asked questions
How do you urgently locate a dormer leak without demolition work?
We combine thermography, smoke test, dye test, endoscopy, and precise moisture measurement to pinpoint the source of the leak in your dormer without any demolition or breaking work. Think of seams in bitumen or EPDM, leaking lead flashing, cracks around the frame and fascia board, open gaps at the side walls, or a clogged rainwater drain. In the event of rain penetration, we simulate wind and precipitation with a controlled spray test for a conclusive diagnosis.
As Ultrices Leak Detection, we are at your doorstep nationwide within an hour, day and night. With VCA VOL and NEN 3140 certification, we work safely and deliver a substantiated expert report. Our success rate is 99 percent, and if no solution is found, you pay nothing. If you want to take decisive action on ceiling leaks, also check out thermographic inspection for ceiling leaks or read more about detecting rainwater penetration on the facade.
How much does it cost to detect an urgent dormer leak, and what about insurance?
We provide a free, customized quote within 24 hours. The price depends on the accessibility of the dormer, the type of roofing, the required measurement methods, and any night or weekend work. You receive clear rates in advance, completely risk-free thanks to our no solution, no payment policy.
We work with Dutch buildings insurers and deliver an expert report within three days, including photos, measurements, and repair advice. Leaks that occur suddenly and unexpectedly are often covered, depending on your policy and conditions. We help complete your file. If you want to arrange everything for your claim in advance, view the report for facade leakage insurance.
What signs betray a leaking dormer and what can you do yourself immediately?
Look out for brown circles in the attic ceiling, damp streaks along the dormer frame, soft spots in the fascia board, a musty smell, or drips after rain and wind. Mold on the side walls, peeling sealant edges, and moisture at the junction with roof tiles or roofing are also clear indications.
Until we arrive, you can collect water, move fragile items, and tightly cover the leaking area with a tarp without using sharp objects. Take photos for insurance purposes and switch off the power in areas with visible wet spots around fixtures or outlets to stay safe. We will then take over the full leak detection and reporting for you, supplemented with an emergency seal if desired.
Do you also carry out emergency repairs, and how quickly can you be on site?
Yes, in addition to leak detection, we provide immediate emergency sealing when necessary. This includes a temporary EPDM patch, sealing open seams, refreshing critical sealant edges, securing a clamping strip, or clearing the rainwater drain so that your dormer remains dry. This prevents subsequent damage until the final repair round.
We operate nationwide and are usually with you within an hour. You benefit from professional detection equipment, fifteen years of experience, five-out-of-five stars in customer reviews, and detailed repair advice with a cost estimate. All without disruptive demolition, fully transparent, and focused on rapid damage mitigation and a sustainable solution.
